ROTARY TABLE.

To all whom it may concern:

Be it known that I, JAMES H. QKELL, a citizen of the United States, IBSldlIlg at Los Angeles, in the county of Los Angeles and State of California, have invented newis particularly adapted to. be used for ro- V tating the boring rods and barrel heads in w oil wells.

The object of this invention is to provide a simple and efiicient means for lubricating rotary tables usedfor turning the boring rod and head in oil wells during a boring operation, thereby reducing to a minimum the friction of the thrust and in the bearing, as well as eliminating undue wear and noise.

Other objects will appear in the following description, will be pointed out in the claims and will be embodied in the accompanying drawings, in which:

Figure 1 is a plan view of a rotary tabl embodying my invention.

Fig. 2 is a vertical section of the same, taken on the line 2-2 of Fig. 1.

In carrying out my invention I employ a bearing member 5 which comprises an annular sleeve 6 provided with the bore 7 and outwardly projecting ears 8 adapted to be supported on and secured to bars or timber 9, conveniently located at the head of an oil well. An annular outwardly projecting flange 10 is formed around the top' edge of sleeve 6 and is provided with an annular trough or groove 11 in its top surface.

Mounted to rotate in bore 7 is the boring rod sleeve 12, which is provided with an annular outwardly projecting flange 13 adapted to rest upon flange 10 of sleeve 6 and over trough-or groove 11. The outer annular surface of flange 13 is provided with gear teeth 14 adapted to mesh with the teeth of a drive pinion 15 shown in dotted lines in Fig. 2. The sleeve 12 is provided at its lower end with a retaining collar 17 which is secured thereto by'means of a set screw 16. By this construction the sleeve Specification of Letters Patent. Patented June 21, 1921, Application filed March 20, 1920. Serial No. 367,830.

12 is held from vertical. movement with respect to the sleeve 6.

The top surface of the flange 10 of sleeve 6 1s provided with a plurality of radially disposed grooves 18 which cross the annular groove 11 and are of a slight depth as compared with the depth of said roove 11.

Secured to the upper surfaceo flange 13 are the oppositely disposed upwardly projecting socketed members 19 adapted to receive the usual posts (not shown) to which the boring tool (not shown) may be secured, 1n order that it may be revolved with the sleeve 12 and also adjusted vertically therein.

In operation the trough or groove 11 is kept fullof lubricating oil and as the sleeve 12 is revolved, the vibration as well as capillary attraction will cause the oil to be slushed upon or attracted to the under surface of flange 13 and to thereby gradually pass through the grooves 18, thus suplying oil between the thrust contact surace of members 10 and 13 and between the 'outer' peripheral surface of sleeve 12 and the inner peripheral surface of sleeve 6.

By the above recited construction it will be seen that all of the movable contacting parts will be efliciently and continuously oiled, thereby'avoiding the necessity of the use of expensive ball bearings, as well as dispensing with the objectionable noise usually accompanying the boring operation.

What I claim is:

A rotary table, comprisingv a bearing sleeve provided on its upper end with an annular groove and a plurality of radial grooves formed on the upper end of said sleeve and intersecting said annular groove, a boring sleeve provided with a flange adapted to rest on the upper end of'said bearing sleeve, and detachable means secured to the lower end of said boring sleeve for maintaining the flange of the boring 1 sleeve in contact with the upper end of the bearing sleeve.

In witness that I claim the foregoing I have hereunto subscribed my name this 21st day of February, 1920.

JAMES H. OKELL.
